Understanding Ethereum Mining Economics
Ethereum mining operates on fundamentally different principles than Bitcoin, yet shares similar cost calculation methodologies. Let's break down the key components:
Core Components of Mining Costs
- Hardware Investment - Initial purchase of mining equipment
- Power Consumption - Ongoing electricity costs
- Operational Lifespan - Typical 3-5 year viability window
- Network Difficulty - Fluctuating mining competition levels

Ethereum Mining Hardware Specifications
The CW588 mining rig serves as our reference model:
| Specification | Detail |
|---|---|
| Theoretical Hashrate | 236 MH/s |
| Actual Hashrate | ~225 MH/s |
| Power Consumption | 1,150W ±5% |
| Initial Cost | ¥10,200 (~$1,450) |
Hashrate Explained
Ethereum's current network hashrate sits at 193 TH/s - equivalent to just two Bitcoin mining rigs. This relative stability makes cost projections more reliable than Bitcoin's volatile difficulty adjustments.
Calculating 3-Year Mining Costs
Power Expenditure Breakdown
- Hourly consumption: 1.2 kWh
- Daily usage: 28.8 kWh
- Annual consumption: 10,512 kWh
- 3-Year total: 31,536 kWh at ¥0.36/kWh → ¥11,352 (~$1,620)
Total Investment
- Hardware: ¥10,200
- Electricity: ¥11,352
- 3-Year Total: ¥21,552 (~$3,070)
Mining Yield Projections
Daily Production Estimates
- Per MH/s reward: 0.00008605 ETH
- 225 MH/s rig yield: 0.0194 ETH/day
- Annual production: 7.06 ETH
- 3-Year projection: 21.2 ETH
Factoring in expected network changes (30% hashrate reduction from legacy hardware retirement), actual yields may reach ~30 ETH over three years.

Break-Even Analysis
- Cost per ETH: ¥1,016 (~$145)
- Current market price advantage: ~38% below spot price ($234)
- Key Insight: Mining provides cost basis advantage during stable markets
Shutdown Price Determination
Critical Calculation
Using ¥0.36/kWh electricity:
- Daily power cost: ¥10.37 (~$1.48)
- Break-even requires: 0.0107 ETH/day (10.37/1016)
- Shutdown threshold: When daily yield <0.0107 ETH
FAQ: Ethereum Mining Essentials
Q: How does Ethereum 2.0 affect mining viability?
A: Current projections suggest PoW mining may continue for 3-5 years post-upgrade, with gradual phase-out.
Q: Why is joint mining beneficial for small operators?
A: Risk-sharing models eliminate upfront operational fees, only taking 30% of profits after 110% ROI.
Q: How does hashrate stability impact cost calculations?
A: Ethereum's relatively stable network difficulty allows more reliable long-term projections than Bitcoin.
Q: What factors could improve mining profitability?
A: Hardware efficiency gains, electricity cost reductions, or ETH price appreciation all positively impact returns.
Q: When should miners consider upgrading equipment?
A: When newer models provide at least 30-40% better efficiency (hashrate/watt) to justify capital expenditure.
Q: How does temperature affect mining operations?
A: Cooler environments improve hardware efficiency and longevity, potentially reducing downtime costs.
